'WELL PUMPING APPARATUS.

APPLIOATION FILED DEC. 21, 1910. RENEWED MAR. 19, 1912.

1.042,,33Q. Patented 001. 22, 1912.

35 tions might be made in the herein described the air, the dynamic efl'ect by the upward rush of air, and the ejector efl'ect causedby the flow of air and liquid upward from them ner cone C, causing the. liquid to sucked upward in the annular space between said inner cone and the shell A.

'When it is desired to discontinue the pumping action, if the handle G is turned to the position indicated by the numeral 1 in Fig. 1, the cam plate H will release the air valve I, which will snap to on its seat, will open the exhaust valve K, and will release the valve N, which will also snap to on its seat, so that this time the interior of the well will be open to the exhaust and the air pressure will be relieved therein, permitting the liquid to seep in through the perforated cone, as before. When itis desired to keep the air pressure on the well for any length of time, by keeping the arm P of the bell crank lever P in the raised position, the handle G cannot be turned, as by'accident,

or carelessness, to the'position for opening the exhaust,

It will be noted that the only valve whose stem requires any packing is the stem of the air valve M.

It will be obvious that various modificaapparatus,'which could be used without departing from the spirit of my invention.

' Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is":

1. A well pumping apparatus comprising an outer tube, adapted to admit liquid at its lower end. a cap normally closing the upper end of-said tube and provided with liquid delivery and; air exhaust ports, respectively, and, also with an inlet passage for compressed air, an inner tube projecting downward into said outer tube and connected at its upper end to said air passage in said cap. valves normally closing said air passage and said liquid delivery and air exhaust ports, respectively, and a hand operated cam arrangement controlling said valves, substantially as described.

2. A well pumping apparatus. comprising an outer tube, adapted to admit liquid at its lower end. a cap normally closing the upper end of said tube and provided with liquid delivery and air exhaust ports, respectively. and also with a passage for compressed air, an inner tube proiecting downward into said outer tube and connected atits upper end to said. air passage in said cap. sprin impressed valves normally closing said air passage and said liquid delivery and air exhaust ports, respectively, and a cam plate and also with a passage for compressed air, an mner tube pro ect1ng downward into said lever pivoted contiguous to said handle, and

having its arms in different-planes, wherebysaid lever arms form successive stops for said handle, substantially as described.

4. A. well pumping apparatus, comprising an outer tube, adapted to admit liquid at its lower end. a cap normally closing the upper end of said tube and provided with liquid delivery and air exhaustports, respectively,

"and also with a passage for compressed air,

aninner tube projecting downward into said outer tube and connected at its upper end to said air passage in said cap, an inverted cone mounted below andspaced from the lower end of said inner tube, valves nor- -mall v closing said air passage and said liquid delivery and air exhaust ports, respectively, and a hand operated cam arrangement controlling said valves, substantially as described.

' 5. A well pumping apparatus comprising an outer tube, a perforated inverted conicaltip secured to the lower endvof said tube, and adapted to admit liquid at its lower end. a cap normally closing the upper end of said tube and provided with liquid delivery and air exhaust ports, respectively, and also with an inlet passage for compressed air. an inner tube projecting downward into said outer tube and connected at its upper end to said air passage in said cap, valves normally closing said air passage and said liquid delivery and air exhaust ports, respectively, and a hand operated cam arrangment controlling said valves, substantially as described. v

6. A well pumping apparatus comprising an outer tube, a perforated inverted conieal tip secured to the lower end of said tube, v

and adapted to admit liquid at its lower end.

noeasso a passagefor compressed air, an inner tube projecting downward into said outer tube and connected at its upper end to said air passage in said cap, spring impressed valves normally closing said air passages and said liquid delivery and air exhaust ports, respectively, and a cam plate pivoted in said cap and adapted to open either said air valve alone, or both said air and said liquid valve, or said exhaust valve alone, substantially as described.

7. A well pumping apparatus comprising an outer tube, a perforated inverted conical tip secured to the lower end of said tube and adapted to admit liquid at its lower end, a cap normally closing the upper end of said tube and provided with liquid delivery'and air exhaust ports, respectively, and also with a passage for compressed air, an inner tube projecting downward into said outer tubb and connected at its upper end to said air passage in said cap, spring impressed valves normally closing said air passage and said liquid delivery and air exhaust ports, respectively, and a cam plate pivoted in said cap and adapted to open either said air valve alone, or both said air and said liquid valve, or said exhaust valve alone, a handle for turning said cam plate, and a bell crank lever pivoted contiguous to said handle, and having its arms in different planes, whereby said lever arms form successive stops for said handle, substantially as described.

8. A well pumping apparatus, comprising an outer tube, a perforated inverted conical tip secured to the lower end of said tube and adapted to admit liquid at its lower end, a cap normally closing the upper end of said tube and provided with liquid delivery and air exhaust ports, respectively, and also with a passage for compressed air, an inner tube projecting downward into said outer tube and connected at its upper end to said air passage in said cap, an inverted cone mounted below and spaced from the lower end of said inner tube, valves normally closing said air passage and said liquid delivery and air exhaust ports, respectively, and a hand operated cam arrangement controlling said valves, substantially as described.

In testimony whereof, I afl'ix my signature, in presence of two witnesses.
